摘要
利用土壤源热泵实验系统,进行不同埋管间距下冬季连续运行实验。采用FLUENT模拟软件建立竖直U型埋管的等效传热模型,对不同实验工况进行了数值模拟,将获得的实验数据与模拟结果进行对比分析。通过分析,得到了不同埋管间距对土壤源热泵系统性能的影响,土壤温度场变化对地埋管换热器换热性能的影响规律。
Based on the experimental ground source heat pump system, researches of winter continuous operation underdifferent experimental borehole spacing were done. A vertical U-shaped ground heat transfer equivalent model was es-tablished by FLUENT software. Numerical simulation with different experiments were analyzed. After that, experimen-tal data and simulation results were compared. Performance affects with different buried tube space and the influence ofheat transfer performance of vertical buried tube heat exchanger with soil temperature changes were analyzed.
